LibreS3 is a robust open source implementation of the Amazon S3 service, supporting a subset of the S3 REST API. Standard S3 client libraries and tools (for example python-boto, s3cmd, DragonDisk, etc.) can
be used to access it. LibreS3 uses Skylable SX as the storage backend, which automatically provides data
deduplication and replication.

Ubooquity is a lightweight and easy-to-use home server for your comics and ebooks. It allows access to your files from anywhere, with a tablet, an e-reader, a phone, or a computer. Ubooquity offers a Web administration page (if you prefer to do everything through your browser), user management with secured access (to decide who can see what), and an online comic reader (to read your comics without downloading huge files), and it supports many types of files, with a preference for epub, zip (cbz), rar (cbr), and PDF files.

Skylable SX is a reliable, powerful, fully distributed cluster solution for your data storage needs. It can aggregate the disk space available on multiple servers and merge it into a single storage system. The cluster makes sure that your data is always replicated over multiple nodes (the exact number of copies is defined by the sysadmin) and synchronized. It has built-in support for deduplication, client-side encryption, on-the-fly compression, and much more.

JS-Collider is an event-driven Java network NIO framework. It is designed to provide maximum performance and scalability for applications having not too many connections but significant amounts of network traffic (both incoming and outgoing). Performance and scalability are achieved via lock free algorithms and atomic states usage. It supports UDP (with multicast) as well. One of the implementation points is to avoid unsafe cheating; it should work the same way on all JVMs (Java 1.7). It supports shared memory IPC.

Paranoid TelnetD is written in straight C with few dependencies. It is intended for use with embedded or legacy devices (like the hand-scanners used in warehouses) that communicate via telnet. It features: 'telnet only' user accounts, separate from the system authentication (so only the specified usernames/passwords can login via telnet, and only via telnet); user, IP address, and MAC address whitelisting/blacklisting; chrooting with 'bind mounts' to allow access to certain directories under the chroot jail; and 'honeypot mode' in which all authentication fails and all events are logged at syslog 'crit' level.

OAQL Server allows you to connect, on all your networks, all your Java applications and all your SQL/NoSQL databases (from different suppliers), as if you had a single application/database in an oriented architecture environment.

The X2Go Server allows you to connect to and control your machine from a remote computer running the X2Go Client. You can simulate a complete desktop session or run individual remote applications as if they were running on your local machine. The protocol is secure (via SSH) and very responsive, even over a very slow connection.

Arduino Gopher is an arduino .pde that lets you run a gopher server on an Arduino Uno with Ethernet shield. It has a simple guestbook function so that people can leave a message that will be stored in EEPROM. It also shows DAC voltages and lets you toggle digital outputs.
